Abstract

We report a case of chromophobe cell renal carcinoma. A 59-year-old female was admitted to our hospital with asymptomatic gross hematuria. Abdominal computerized tomography showed an approximately 4 cm. minimally enhancing mass in the left kidney. Angiography revealed a hypovascular tumor in the left kidney. Under the diagnosis of renal cell carcinoma, left radical nephrectomy was performed. The cut surface of the tumor was beige in color with few foci of hemorrhage and necrosis. Microscopically, the tumor was composed of the cells with voluminous reticulated cytoplasm stained lightly with routine hematoxylin and eosin. Hale's colloidal iron staining demonstrated a positive cytoplasmic reaction. Pathological diagnosis was chromophobe cell renal carcinoma. Chromophobe cell renal carcinoma is a recently established subtype of renal cell carcinoma, which has rarely been reported in Japan.
